DRINKING WATER CASE STUDIES AND WHITE PAPERS

• Instrument Resiliency For Tough Times

  Utilities have relied on numerous instruments for process control and monitoring for many years. But in today’s world, instrumentation is more crucial than ever. Most treatment facilities, pump stations, and other system components are automated to some extent. Instrument failure or inaccuracy may result in serious public health or environmental consequences. Resilient instruments can power through adversity and keep utilities running smoothly.

• Flow Data Red Flags: When To Act

  Accurate flow measurement is critical to most water and wastewater processes. Red flags may pop up to indicate meter problems, but which ones should lead you to act — and when? The answer depends on the type of meter, what it is used for, and whether the readings are local or remote.

• Four Day Pilot Study For Iron And Manganese Does The Trick (Loprest)

  The City of Southgate, California wanted to investigate the effect of replacing the existing media in their Well 27 treatment plant. The plant would not reduce the incoming manganese levels to below the 50 μg/l MCL. It has been theorized that the existing media has become fouled beyond cleaning during the one year plus of non-operation while contained in the filter tank full of water. That environment could produce a likely source of biological and other sources of fouling.

• Mastering The Application Of UV Advanced Oxidation Using Chlorine In California

  The Water Replenishment District of Southern California (WRD) is the largest groundwater agency in the State of California, managing local groundwater resources for over four million residents in South Los Angeles County. Learn about the new water treatment facility that they constructed which has allowed the region to be entirely self-sufficient in times of drought.

• The Differences Between UV AOP & Granular Activated Carbon For Contaminant Treatment

  Providing safe drinking water is a growing challenge. There are certain chemical contaminants resistant to traditional water treatment methods which are being detected in drinking water – with the potential to impact public health.

• Advantages Of Thermal Dispersion Switches For Pump Protection

  Thermal dispersion switches use similar principles as thermal mass flow meters. Fluid carries heat away from the probe tip reducing the temperature difference between a heated resistance temperature detector (RTD) and a reference RTD.

• Got Water? Regional Water Supply & The Economy

  Got water? Sure, most of us in the United States do. But do we ever stop to smell the roses of odorless fresh potable water? Do we reflect on what reliable water means for the economic life of our community? Texas’s harsh deep freeze earlier this year reminded us Texans of our vulnerability, and after $200B in damages, it gave us a glimpse of how life looks without the core services that we take for granted daily.

• Is Transitioning From AMR To AMI Worth The Effort?

  For the City of Fairborn, Ohio, switching from manual meter reading to automated meter reading (AMR) and eventually to advanced metering infrastructure (AMI) has made a small operations staff more productive, provided more timely information for the city’s water treatment plant and distribution system, and tremendously improved customer service. Learn about the benefits captured and lessons learned along the way.

• Applications Where Variable Area Flow Meters Deliver Value And Performance

  Learn why Variable Area flow meters are the technology of choice where simple, dependable performance and cost advantages are important.

• Hydra-Stop Solutions Isolate Damaged Valve During Water Main Replacement

  The Village of Covington, Ohio had an ambitious 90-day project to replace the water main, taps, sewer main, laterals, and storm sewer through the center of town. Unfortunately, on day one, an unknown water service line was snagged and the top half of an 8” valve blew off, causing water to shoot 10”–12” out of the street.
